Frequently asked questions
How far can one CN901 extend the signal?
The listing states a typical 100 m extension per relaying unit. Check the complete link and cable installation rather than assuming unlimited distance through additional repeaters.
What do the three CN901 LEDs indicate?
LED 1 indicates the nearer network-port signal, LED 2 the farther network-port signal, and LED 3 power.
Does CN901 replace the LED sending card?
No. It extends the signal path between compatible sending and receiving cards. The display still needs its sending and receiving equipment.
